IPC: G06F7/52
Filed: 1989-04-03
Abstract: The position multiplication circuit according to the subject of the invention is a multiplication circuit which has as its main parts four times circuits (1 to 4), and also an adder circuit (5) as an additional main part. Times circuit (1) supplies the 2 times number value. Times circuit (2) supplies the 3 times number value. Times circuit (3) supplies the 4 times number value. Times circuit (4) supplies the 5 times number value. The 6 times number value is formed using the direct circuit (8) and times circuit (4), i.e. 1 + 5. The 7 times number value is formed using times circuits (1 and 4), i.e. 2 + 5. The 8 times number value is formed using times circuits (2 and 4), i.e. 3 + 5. The 9 times number value is formed using times circuits (3 and 4), i.e. 4 and 5. Thus a maximum of two times circuits is required for a multiplication. These combinations have the advantage that only one dual half adder (9) is required in the area of the first tetrad. <IMAGE>

Patent DE-3920982-A1 (DE)
Inventor: TERKOWSKI JUERGEN
IPC: H04M1/65
Filed: 1989-06-27
Abstract: 2.1. Subscriber devices in the form of answering machines with information recording, call forwarding and remote interrogation are known. If the owner of the answering machine is travelling, the call signal, after the message of the caller has been recorded, can be automatically forwarded to a paging receiver via the European paging service. The answering machine contains an automatic dialler for forwarding the call. Furthermore, a paging service (City-Ruf) is known in which not only paging signals but also digits and short text (Display-Paging) are transmitted and displayed on the display device of the paging receiver. 2.2. Using a network gateway from the line-connected telecommunications network to a radio paging service, the novel subscriber device provides for fast information transmission of messages temporarily stored in the subscriber device. For this purpose, the subscriber device contains, in addition to the additional buffer store, a microprocessor which, using stored dialling information items, sets up a connection to a paging receiver and then reads out the temporarily stored message. 2.3. The novel subscriber device can be used in all communication networks for switched connections and ensures that a called subscriber who is travelling can respond quickly to a call. <IMAGE>

IPC: C07C67/03
Filed: 1991-07-19
Abstract: Oils or fats, in particular of vegetable, but also of animal origin, are reacted with methanol or ethanol and an alkaline catalyst in the liquid phase. Glycerine and methyl esters of fatty acids or ethyl esters of fatty acids are formed. The reaction is carried out using at least two reaction steps, each reaction step having a mixing reactor and a separator for the separation of a light, ester-rich phase and a heavy, glycerine-rich phase. The oil or the fat, the alcohol and the catalyst are added to the mixing reactor in the first reaction step and these substances are intensively mixed. The alcohol and the catalyst as well as the light, ester-rich phase obtained in the preceding reaction step are added for intensive mixing to the mixing reactor in the second and each further reaction step. A heavy phase is separated in the separator in the second to last reaction step and at least partly fed back to the mixing reactor in the first reaction step. Methyl esters of fatty acids or ethyl esters of fatty acids are obtained from the light, ester-rich phase separated in the last reaction step by at least one further separation treatment. The process is preferably carried out using two reaction steps. <IMAGE>

Abstract: A swinging drawbar (32) is provided for a driven device, in particular for an agricultural vehicle or utility vehicle, in which drawbar (32) the coupling point can be adjusted to at least two different working lengths. In order to permit simple adjustment to different working lengths and to permit the coupling point to be conveniently seen from the driver's seat during the coupling process, optional locking means (86, 88, 110) which correspond to the different working lengths are attached at positions (78, 80, 82, 84) in such a way that during the longitudinal displacement of the swinging drawbar (32) automatic locking takes place when the selected working length is achieved. Preferably, a cartridge (22) is used which can be attached to the vehicle, and has transverse grooves (110) and into which the swinging drawbar (32) can be inserted. Locking noses (102, 104) which are formed onto claws (86, 88) engage in the transverse grooves (110). The claws (86, 88) can be mounted at different positions of the swinging drawbar (32).

Patent DE-4140066-A1 (DE)
IPC: B60T13/565
Filed: 1991-12-05
Abstract: The proposal is for an actuating unit for a hydraulic braking system consisting of a pneumatic servobrake and a master cylinder fitted downstream thereof, the piston of which delimits a hydraulic pressure chamber and which has an annular piston of greater diameter effectively coupled to the piston which delimits a filling chamber connectable to the pressure chamber. To ensure that the actuating unit operates with a clearly definable changeover pressure and free travel independent of the actuation speed, the invention proposes that the annular piston (23) be separable from the piston (19) if the hydraulic pressure acting upon it reaches a predeterminable value. This ensures that the shift in the filling chamber by the annular piston does not extend over the entire master cylinder stroke.
